VENDING-MACHINE.

SPECIFICATION formingpart of Letters Patent No. 742,527, dated October 27, 1903.

Application filed March 22, 1902. Serial No. 99,528. (No model.)

To all whom it may concern.-

Be it known that I, FRANK M. TRAINER, of Weymouth, in the county of Norfolk and State of Massachusetts, have invented a new and useful Improvement in Vending-Machines, of which the following, taken in con'- nection with the accompanying drawings, is a specification.

My invention relates to that class of mechanisms in which the placing of a coin in a slot releases certain parts, and thus causes it to perform the desired function; and it consists in certain details of construction and arrangement by the aid of which certain functions will be performed.

The construction and arrangement may be best understood by examination of the drawings and specification.

The mechanism and operation of my apparatus are illustrated in the accompanying drawings, in which- I Figure 1 is a vertical longitudinal section taken through the center of my apparatus. Fig. 2 is a front elevation of the same. Fig. 3 is a view partly in side elevation and partly in vertical longitudinal section. Fig. 4 is a vertical cross-section taken on line X X of Fig. 1. Fig. 5 is a plan of my apparatus. Fig. 6 is a horizontal section taken on line 4 4 of Fig. 3, except that a part of the pushrod is shown in full, (pushed in.) Fig. 7 is a partial horizontal section showing the'action of the apparatus in case a washer or disk with a hole in its center is placed in the slot. Fig. 8 is a partial horizontal section showing the action of the apparatus in case a soft (lead,

for instance) disk is placed in the slot.

My apparatus is inclosed in and attached to a casing and framework, which is indicated in the drawings by the letters A A A and so on.

0 represents a chute in which the slot 0 receives the coin which is to admit of the operation of the parts.

B is a tube mounted upon the top of the rear end of the case A and is adapted to receive the article 13 B to be sold,and B is the opening through which the article to be delivered is pushed.

The main operatingparts of the device consist of the push-piston D, which slides in an net M'MM.

opening made in the head-plate A, and its attachments.

D D constitute a moving head-piece and is connected directly to the push-piston D.

A small rod E is inserted in theinner end of the push-piston D and has a slight longitudinal motion, its end resting against the disk D3, which is kept in place by the spring D in the interior of the push-piston D. The said rod E has at its inner end a pin E which extends loosely through the piece L and is headed, so as to prevent the piece L from separating from it. The piece L can slide back and forth on the said pin E Thus in Fig. 1 this piece L is shown at a short distance from the face of the head-piece D and in Figs. 6, 7, and 8 it is shown in contact with the said face. as 'a back support for the coin T and as a holder for the front support K, which is pivoted at K to it. The coin T is held between the two supports L and K, as shown in Figs. 1 and 6. The upper part D of the headpiece is inclined, so as to receive the coin as it passes down the chute O and assist in di= recting it into its place between the supports K and L. The front support K has an arm K which acts as a lever when it comes in contact with thelower part of the head-piece 'D and forces the front support to clamp the coin and thus assist in holding it while it is being pushed forward. The upper part D of the head-piece is made narrow, as shown in Fig. 5, and is located when the push-piston is forced out to its limit by the mainspring S between the two arms of the U-mag- (See Fig. 1.) The object of this magnet will be explained later.

A door E Figs. 3, 4E, and 6, is set in the side of the coin-chamber. This door swings upon a pivot (shown at its loft-hand end, Fig. 6) and is closed by a spring E and in some cases looked, as will be hereinafter explained, by a locking-pin E Fig. 3. This door E is constructed to swing horizontally on a pivot, one end of which is shown near the left hand of said door, Fig. 5, and is kept nermally closed by the spring E The device for locking the door E consists of a pin E Fig. 3, which will drop out of locking engagement by its own weight unless held in place by the lever E.

The said piece L serves It is to be observed that when the forward motion of the push-piston begins the lever E is in the position shown in Fig. 1-thatis, its end is under the pin E (see Figs. 2 and 4) and as soon as the parts advance and the pin E is held back by a genuine coin then the upper end of the bent lever E will be held back, (see Fig. 6,) causing the long end to come in contact with the pin E (see Figs. 2 and 4) and to throw it up, thus locking the door E The first movement of the push-piston D will cause the coin T to move along and to meet with some frictional resistance, caused by coming in contact with the spring d, which has a tendency to force the coin (edgewise) against the opposite side of the case. This holding back of the coin at first will cause it to prevent the forward motion of the pin E and through it the short rod E, and as the rod E engages with the arm of the bent lever E, pivoted at E the said lever will push against the locking-pin E (see Fig. 3) and eauseit to look the door E which is otherwise yieldingly held by the spring E Now as the coin advances, being pushed by the push-piston, it cannot be forced out sidewise, as the door'E is locked, but will advance and engage With the projections h it (see Figs. 1, 4, and 6) on the slide H. As soon as the coin engages with the slide II it in its continued motion forces the said slide H and its spring prolongation H H (see Fig. 1) to move toward and against the article 13 to be ejected and pushes it out. During the forward movement the coin will reach the opening R and drop into any receptacle that may be provided for it. As

soon as the pressure is removed from the pushpiston D the spring S on the rod A will, acting on the projection D force the coin-holding parts back to their original position--that is, the position shown in Fig. 1. The arm H H of the slide H isaspring and yields, so that it will draw back under the article B next to be ejected without disturbing it and will spring up ready to take the article at its next forward movement. served that in case there is no full disk or coin in the space between the supporters L and K-that is, in the casethe slide H will not be affected by pushing in the push-piston D.

The above description relates to the working of the apparatus when a genuine coin is inserted in the slot. I will now describe the action in case a fraud is attempted. Forinstance, suppose an iron disk is inserted in the slot. As soon as the disk reaches the face of the U-magnet M M M it will be stopped and held on the incline by magnet attraction and not fall into the case A at all. When the push-piston is pushed in, the iron disk will be carried along on the incline D remaining on top of the case A, with its lower edge resting on the fixed strip A resting against the part 01 but as the part (1 does It should be ob-' not move there will be nothing to prevent the disk from falling out of the open side.

' As an additional device for insuring the falling ofi of the iron disk I have a longitudinal strip A, fixed on the top of the case A. This strip is not on the center, but at one side, as shown in Fig. 5, so that the disk will not be balanced upon it, but will fall or roll off at one side. Another safeguard consists in the catch A ,which if from any cause the disk has not fallen olf will catch the disk on the return of the push-piston and prevent it from falling into the slot. disk is inserted, it will as the parts are forced forward (see Fig. 8) come in contact with the spring (1 and be bent, so that its edge will not engage with the projections h h on the slide H, and thus pass by without causing the slide to move. Hence no article B will be ejected and the fraudulent disk will drop out at R. The front of the back support L is cut away, as shown in Fig. 8, to admit of bending back of the lead disk. Now suppose that a Washer is dropped into the slot. It will fall into its place between the supports L and K; but as the piston is moved forward the pin E will meet with no obstruction, as it will pass through the hole in the Washer. Hence the rod E will remain relatively stationary and the lever E will not be acted upon. Hence the door E will not be locked and the spring (1 will force the fraud washer laterally out, forcing the door E open, and any further movement of the push-piston will be without effect upon the slide H. In case a disk of less diameter than the required coin is inserted then the spring at will force the said disk to one side, so that it will not engage with the projections h h on the slide H.

The slide H is connected to the push-piston head by a wire h and the projection d. The Wire slides freely through a hole in the said projection, its end being headed or bent, so as not to become disconnected. The spring C Figs. 1 and 3, serve to prevent the passage of a coin when the head'is pushed forward.

I claim- 1. In avending-maohine, apush-piston and head; coin-holder; a slide having projections constructed to engage with the edge of a genuine coin; a spring d, constructed to engage with the edge of a disk of smaller diameter than that of the genuine coin, and to force it away from the said projection; substantially as and for the purpose set forth.
